[pigleto972001]

it's ceramic, here's the spiel from chanel.com:


A CHANEL bestseller since its launch in 2000, the J12, the brand’s first sport watch, now has a mirror image. The deep black version has undergone a metamorphosis to opalescent white to amazing effect. Sheer beauty, perfect balance, white ceramic enriched with white pigments to give it a quasi-polar, almost unreal colour, with its radiance heightened by numerals, hands, date display and inscriptions...in black.

The J12 white ceramic model is available in:
- 38 mm diameter, Swiss automatic movement:
Classic - Ref: H0970 Set with diamonds - Ref: H0969
- 33 mm diameter, Swiss high-precision quartz movement:
Classic - Ref: H0968 Set with diamonds - Ref: H0967
